Radiums right, except that you wouldn't be using 100% against a normal turtle. You wouldn't even care about him. (heck) you could even walk right up and jump over him. Plus its rare I ever play co-op, except with my little sister, who usually runs out of lives and dies before the buba boss, or on him. (just about anywhere in the cold heck lvl) It would be pretty cool if you could play coop on-line, with 18 rabbits blasting the crap out of everything in sight.(except for the coin problem)
I tr and play may best at CTF, except during duels.
Don't forget Hide n Seek mode
(if its still around)
